Automatic speed limiter

The Automatic Speed Limiter (ASL1) function helps the driver to adapt the car's maximum speed to the speed shown on the road signs.

The Speed Limiter function (SL2) can be changed to Automatic Speed Limiter (ASL).

The automatic speed limiter uses speed information from the Road Sign Information (RSI3) function to automatically adapt the car's maximum speed.

 Warning

Even if the driver clearly sees the speed-related road sign, the speed information from the Road Sign Information to automatic speed limiter function may be incorrect – in such cases the driver must intervene him/herself and accelerate or brake to a suitable speed.

 Warning

  • The function is supplementary driver support intended to facilitate driving and make it safer – it cannot handle all situations in all traffic, weather and road conditions.
  • The driver is advised to read all sections in the Manual that relate to this function to learn about factors such as its limitations and what the driver should be aware of before using the system.
  • Driver support functions are not a substitute for the driver's attention and judgement. The driver is always responsible for ensuring the car is driven in a safe manner, at the appropriate speed, with an appropriate distance to other vehicles, and in accordance with current traffic rules and regulations.
